Abstract
A wireless communication device includes a data receiving interface, a data processing device coupled with the data receiving interface, and a processing device coupled with the data receiving interface. The data receiving interface is configured to receive a first sub-group and a second sub-group of data for transmission. The first sub-group of data includes data contents for providing at least a portion of a first service, and the second sub-group of data includes data contents for providing at least a portion of a second service. The data processing device is configured to combine the first sub-group of data and the second sub-group of data as a portion of a data transmission group. The processing device is configured to provide a size of a first length indicator based at least on a size of the data transmission group. The first length indicator is configured to indicate a size of the first sub-group of data. The processing device is also configured to provide a size of a second length indicator based on one or more numbers or considerations, such as (a) the size of the first length indicator; (b) the size of the first sub-group of data; (c) the size of the data transmission group; and (d) the size of a header section. The second length indicator is configured to indicate the size of the second sub-group of data.
